Hi,nYou can the following:nDo you have an outer Region that enclose everything? This is necessary.nDo you have multiple objects in the band but you did not assign and inner region to enclose the multiple objects?nIf there's only one object in the band, is it hollow or does it have holes? The object in band must be a single, solid object without any holes to break the domain.nIs your Region or band in hollow shape? They can not be hollow or have holes, either. If you have a outer rotor machine, you can rotate the inner stator instead as it's just relative motion, this way your band or region won't be hollow.n
